It is the service established with the purpose of contributing to safety, air traffic ordering and flowingness, to ensure that the demand expectation is balanced with the optimized manner with the practiced capacities.

The responsible authority for the general administration of the air traffic flow management service is the Director-General of the Department of the Airspace Control (DGCEA).

The ATFM Service is provided in all air space that overlays the national territory, including territorial and jurisdictional waters, as well as the air space that has been object of air navigation regional agreement.

4.1. The ATFM Service is planned and developed in the whole responsible area, in a centralized way, by the Air Traffic Management Centre (CGNA), with support of flow management cells (FMC) in all ACC and APP with expressive air traffic demand.

4.2. The Service is provided according to the contained in Annex 11 to the International Civil Aviation Convention – Air Traffic Services, and in ICAO Doc. 4444 - Air Traffic Management.

The following terms and respective meanings shall be considered as ATFM Service provision:

Aerodrome whose air traffic demand forecast is superior to the declared and/or practiced capacity, having, therefore, all landing and departure operations conditioned to ATC SLOT attainment.

NOTE: Any aerodrome can change to the co-ordinated condition on account of an atypical seasonal demand.

Aerodrome whose air traffic demand forecast tends to excced 80% of the declared capacity, being, therefore, all intentions of passenger and/or cargo regular flights as well as those of the postal network conditioned to ATC SLOT attainment.

Balance relationship between the air traffic demand and the declared capacity.

Measurement of the processing capacity of critical airport components (runways, apron or terminal), which may involve people, aircraft, luggage or cargo.

Number of aircraft within a specific portion of the airspace, at a given period of time, taking into account the weather conditions, the configuration of the ATC unit, the operational staff and the available equipment, as well as any other factors that may affect the workload of the controller responsible for the airspace in question.

Maximum value attributed to an airport capacity resulting from ATC and airport capacities.

Value attributed to the capacity of an airport or an ATC section on account of elements availability of its installed infrastructures for a period of stated time.

Maximum number of practicable operations at an airport or control section, continually, for a period of stated time.

Situation in which the demand for air traffic is greater than the declared and/or practiced capacity, in a given time interval.

The number of aircraft requesting ATM system services in a given period of time.

It is the group of units, facilities or support structures to the air navigation in order to promote safety, regularity and efficiency.

It is the facilities group in an aerodrome composed of the Movement Area and terminals for passengers.

It is the group of relative information to a scheduled flight, transmitted or not to an ATS unit.

Defined time for an aircraft to pass over a Position Fix or a landing or takeoff operation.

ATC Slot applied to take-off or landing operation of a certain aircraft from a co-ordinated airport that, on account of its nonuse, can be attributed to another aircraft. The opportunity slot can also be created by flow optimization by an ATC unit.

They are actions established through collaborative decisions, involving CGNA, airport authorities, ATS units and explorers/ operators in order to be applied in unbalanced situations.

6.1.1. Whenever necessary, ATFM measures should be applied to regulate air traffic demand. There are several types of ATFM measures that can be used alone or in combination, depending on the size and duration of the imbalance. As they are normally restrictive actions, the ATFM measures that cause the least impact on users should preferably be applied.

6.1.2. All flight intentions arised from flight programmings and plans will be received, processed and, when necessary, analyzed as for the balancing.

6.1.3. Criteria established for use in Conditioned Airpace can, whenever necessary, under previous coordination, suffer alterations, in view of economy and flowingness air traffic flow.

6.1.4. Seasonal events that can generate additional air traffic demand expectation and produce unbalance will be analysis matter as for the impact in the air trafic flow.

6.1.5. The ATC and airport capacities values can be changed on account of eventual degradations, inoperation or unavailability of elements of their respective infrastructure.

6.1.6. Air traffic management flow measures can reach aircraft on the ground or in flight.

6.1.7. In principle, the management measures will not affect the aircraft in the following situations:

a) emergency;

b) in airspace defense mission;

c) in military operation (war mission or internal safety or military maneuver);

d) carrying or applied to transport sick or wounded people in serious state (ambulance in aeromedical operation, according to specific legislation), needing urgent medical attendance, or transporting vital organs for human transplant;

e) in SAR mission;

f) Flight Inspection mission;

g) transporting State or Government Chiefs; and

h) transporting the Governor of a Brazilian federative unit.

NOTE: The CGNA may exempt other types of flights from applicable ATFM measures.

6.2.1.1. When an AP whose air TFC expectation reaches 80 (eighty) per cent of the adopted capacity, it will be declared through NOTAM as a monitored one and, as a result, all intentions of pax and/or cargo scheduled flights, as well as those of the postal network, will be conditioned to the ATC SLOT obtention; keeping the release to general aviation ACFT which had previously obtained it, except for restrictions of the brazilian civil aviation authority;

6.2.1.2. In a period in which an airport is declared as to be monitored, an allocated ATC SLOT will be compulsory for requiring and/or changing the registered flight from the Brazilian Civil Aviation Authority.

6.2.1.3. Operation at a monitored airport will be conditioned to the following critera

a) coordinate with the airport administration the use of airports facilities of interest and request to the CGNA, an ATC slot, as described on items 6.2.1.1 and 6.2.1.2;

b) the ATC SLOT is valid in the interval corresponding to 5 minutes before to 15 minutes after the expected schedule, except if modified by the ATC unit or account of adverse meteorological conditions or by air TFC flow management measures;

c) informing, previously, the CGNA, in case it is not intended to use an ATC Slot.

d) request a new ATC SLOT, at the local ATC unit, for all schedule changes (EOBT/ETA), except for situations contained in the exception described in the letter B of this item, it will be classified as an opportunity SLOT, with priority reduced to flight accomodation in a low demand time interval;
